Answer:
With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest.
Answer:
The total distance is equal to the change in total position of the person, but the displacement of the person is zero.
Explanation:
- The distance is the total change in the positions of the toy robot. it is having only magnitude and it is a scalar quantity.
- The displacement is the difference between the final and initial position of the toy robot. it is a vector quantity having magnitude and direction
- Since the distance is the change in positions, so the magnitude of the distance will be equal to the up and down distance covered.
- If the toy robot travels in a straight line path and returns back to its original location, the magnitude of the distance and displacement doesn't depend on the speed of the toy robot.
<span>Young modulus E = stress/strain where E is the elastic modulus. We seek to calculate the the strain.
But we would have to get the stress first. Tensile stress = Force/Area. Force = 20100N. And the Area = 9.54* 13.9 = 132.606Nm^2.
Strain = stress/E.where E = 79. Hence we have 132.606/79 = 1.67</span>
It’s c and a I believe ask someone else to make sure but I’m pretty sure
